Astronomers unveiled the most detailed X-ray map of the universe. The map reveals the presence of over 700,000 monster black holes, 180,000 stars, and 12,000 clusters of galaxies.
Germany is behind the creation of the X-Ray map. The data was collected by the eRosita X-ray telescope on board the Spektrum-RG satellite during the first all-sky survey. The first eRosita All-Sky Survey Catalogue (eRASS1) is the largest collection of X-ray sources ever published, the Max Planck Society for the Advancement of Science said in a statement.
The eROSITA All-Sky Survey scanned the universe for six months- from Dec 12, 2019, to June 11, 2020. During this period, the mission detected more than 170 million X-ray photons in the sky, which astronomers later identified as roughly 900,000 distinct objects in space.
Reacting to the mission's findings, eROSITA principal investigator Andrea Merloni said, "These are mind-blowing numbers for X-ray astronomy." Merloni added, "We've detected more sources in 6 months than the big flagship missions XMM-Newton and Chandra have done in nearly 25 years of operation."
